You can monitor the logical port activity for example, to troubleshoot network congestion and packets being dropped

Prerequisites

Verify that a logical switch port is configured. See Connecting a VM to a Logical Switch.

Procedure

  1. From your browser, log in with admin privileges to an NSX Manager at https://nsx-manager-ip-address.
  2. Select Networking > Switching from the navigation panel.
  3. Click the Ports tab.
  4. Click the name of a port.
  5. Click the Monitor tab.
    The port status and statistics are displayed.
  6. To download a CSV file of the MAC addresses that has been learned by the host, click Download MAC Table.
  7. To monitor activity on the port, click Begin Tracking.
    A port tracking page opens. You can view the bidirectional port traffic and identify dropped packets. The port tracker page also lists the switching profiles attached to the logical switch port.

Results

If you notice dropped packets because of network congestion, you can configure a QoS switching profile for the logical switch port to prevent data loss on preferred packets. See Understanding QoS Switching Profile.
